ABSTRACT:
An explosion-proof electrical generator includes a generally toroidal casing with one open end and a central circular end wall or plate or cylindrical fan-containing cup extending across and closing the center of the torus; a circular cover closing the open end of the casing; a stator defined by laminated plates and windings located in the annular recess of the casing; and a rotor mounted in the cover and including a shaft, and a bowl-shaped cup carrying a ring of permanent magnets in its side wall, which extends into the casing recess between the stator and the outer side wall of the casing. Cooling fins are provided on the casing and cover for dissipating heat produced in the generator. The generator has a circuitous or small interior flame path for reducing flame temperature and thus the likelihood of fire or explosion outside of the generator.
